It took me three days to figure out how to install CentOS in Xen with a DVD ISO image of CentOS.

All time I booted from the DVD, the DVD wasn’t found when I should select from which media I want to install. So installing from DVD wasn’t successfull at all. 🙁

The trick is to use the “install from URL” in the XEN VM creation. All you need to do is, mount the DVD into a folder which can be reached via http.
So e.g. you have a linux server with apache installed, mount it to e.g. /home/user/public_html/CentOS via

mount -o loop centos.iso /home/user/public_html/CentOS

Now you can use the following url as “install from Url” in the Xen VM Creation Wizard:

half of the last day, I fought with a C# WebService and the PHP SoapClient implementation.
The SoapClient always send it’s requests always with contenttype “text/xml”, but a C# WebService isn’t smart enough to recognize that it is readable xml but just crys: Uh Oh thats not application/soap+xml … I can’t read that!! I’m very sorry!!

But finally I could tell the SoapClient of PHP to send the request in Application/soap+xml by adding the “soap_version” option to the SoapClient. When you use Soap Version < 1.2 the SoapClient implementation sends the request in text/xml, using the Soap Version 1.2 it sends it in application/soap+xml ...
Hopefully this helps someone!

I always got the following problem when trying to start the firefox-bin:
./firefox-bin: error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory

And finally I found the magic hint which helped:
sudo apt-get install ia32-libs

As the firefox binary of the beta is a 32 Bit one, you will need the compatibility thing for 32Bit, so install the ia32-libs and the problem is gone.
